1. Working principles:LDHS continuous plough shear mixer is widely used in the mixture of chemical materials, pigment, pharmaceutic materials, feedstuff, especially in the mixture of fragile solid grain; In a short time, the mixer has good mixing effect for the materials which has a great difference in grain and density.Its coulter rotates together with main axis and makes the materials radial circling flow along the wall; The radial materials flows through flying cutters, and falls apart by rotating flying cutters; The materials can be mixed uniformly in a shorttime.
